It accepts a 3\/4-inch pilot hole and delivers a length of cut ranging from 5\/8 inch up to 2 inches, making it well-suited for a range of broaching depths. The tool is manufactured from high speed steel (HSS) with an uncoated finish and measures 17-1\/4 inches overall length. It requires up to 6,960 pounds of press force at maximum length of cut. Machinists, toolroom technicians, and fixture builders install this broach using an arbor press or hydraulic press.\u003c\/p\u003e\n\u003cp\u003eThis broach is intended for drive, fixture, jig, and hexagonal broaching operations in industrial and manufacturing environments. It is commonly used when a hex socket or hex bore must be produced to tight dimensional tolerances in ferrous and non-ferrous materials. The across-corners dimension is held between 0.865 and 0.867 inches, and the 3\/8-inch pitch suits standard push broaching setups. Applications include production of hex drives, tooling fixtures, and precision jig components where consistent hex geometry is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch hex form with tight tolerance: 0.750 to 0.752 inches across flats\u003c\/li\u003e\n  \u003cli\u003eAcross-corners dimension held to 0.865 to 0.867 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eLength of cut range: 5\/8 inch to 2 inches to accommodate varying workpiece thicknesses\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel (HSS) construction for durability in push broaching operations\u003c\/li\u003e\n  \u003cli\u003eMaximum press force requirement of 6,960 pounds at full 2-inch depth of cut\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch pitch compatible with standard broaching arbor setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drive, fixture, jig, and hexagonal broaching operations using an arbor press or hydraulic press that can deliver up to 6,960 pounds of force; accepts a standard 3\/4-inch pilot hole in the workpiece.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolroom machinists or skilled press operators using an arbor press or hydraulic press rated for the required force. The workpiece must be pre-drilled to the specified 3\/4-inch pilot hole diameter before broaching. Secure the workpiece firmly in a fixture or vise to prevent movement during the press stroke. Inspect the broach for chips or damage before each use and apply cutting fluid appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.750 to 0.752 inches across flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Hole Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 to 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcross Corners (Min)\u003c\/strong\u003e: 0.865 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcross Corners (Max)\u003c\/strong\u003e: 0.867 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 17-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Press Force\u003c\/strong\u003e: 6,960 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DUMONT MINUTE MAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DUMONT MINUTE MAN","offers":[{"title":"Default Title","offer_id":67911811170610,"sku":"77717","price":987.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c36d043c9f3759b1e39c1c133ab54772.jpg?v=1791220195","url":"https:\/\/voomisupply.com\/products\/dumont-minute-man-77717-hexagon-broach-0-75-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
